  • Raid 5 Recovery

    Hello everyone,

    I need urgent help to recover RAID 5 fault.
    I have Gigabyte MB with Intel Matrix Raid, my system is Raid 5 with 6 WD Black 1 TB HD. Yesterday i get SMART error from disk 0 and then disk 3 been fault.
    I cant get access to my files and i cant rebuild the raid.
    All my DATA on this Raid is only 2.5 TB.

    after a restart i get message that disk 0 is NONE-RAID and disk 3 is fault.
    but when i look in the Intel Storage Matrix i see that disk 0 is NONE-RAID
    and disk 3 is ok.

    Still the raid is broken and i can't repair it

    I will be happy for any help, all my life is on this raid

    Whatever you do, do NOT let anything write data to the drives.
    There are various tools and services you can get:

    (re-search for your country)

    Depending on the value you place on the data, you will spend what is appropriate.
    Also see what is backed up and make sure you can recover from there if you need to.

      Thanks Ossian,
      Yes i know that, but the problem i can't get access to the HD so i can't write on it.
      Also the system can't even rebuild the raid.

      Before i post here i did a search and found a lot of posts about recovering but still
      i don't really know how to recover it.
      So i asked for help, if someone can guide me step by step how to recover my data
      i will be grateful.

        Because the BIOS has lost track of the RAID array, a recovery tool or service will be your only option. Attempting to re-create the array will almost certainly wipe it.

        Look at the link I provided
        Choose a tool
        Read the manual
        Mount your array
        Follow tools instructions to recover data to a separate location.

        Also check your most recent backups... you do have backups?

            Also, you're talking about a RAID5 array, that's suffered a catastrophic loss of two drives.

            RAID5 can only sustain loss of 1 drive. (unless you had a hotspare, I'm guessing you didn't)

            So when the first drive failed, you might have been able to recover it
            the fact that two drives failed at once (unlikely, but not unheard of) means you need professional data recovery.
